Letters Patent No. 111,224, dated January 24, 1871.

lMF ROVEMENT IN CAR-COUPLINGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, JOHN MAYBEN, ofiMih-oy, Mitflin county, State of Pennsylvania, have invented a new and useful Improvement in Gar-Couplings; and I do hereby declare thatthe-following is a clear, full, and exact description of y the construction and operation of the same, reference being had to the accompanying drawing making a part of this specification, in whicht Figure 1 is a side view of coupling-block attached to the bumper.

Figure 2 is a detached view of the coupling-tongue and jaws.

Like letters in the two figures represent like parts of the invention.

Na-twre.

My invention is designed to provide a car-coupling which may be readily changed in height to suit differ-. ent height cars, and consists of a coupling-block eccentrically arranged and attached to the bumper by a bolt, which is arranged above or below the center of the block.

A -is' the coupling-block, made with the large opening B through the side, to allow the tongue 0 to be readily inserted or removed and having the elongated slot, b' at the front end, through which tongue 0 passes; v

The coupling-tongue and jaws 0 are securedat the back end by the bolt :1, so arranged that they can be readily removed for repairs or other purposes.

Block A is provided with a bolt, D, which is arranged above or below the center oftheblock, as seen in fig. l, and passes through the bumper E, and is secured by a proper nut on the end. I

S is a spn'ng attached. to the jaws o by the bolts 0' c, asshown in fig. 2.

flo couple a low car, the longest side, of the block is turned down, as seen in fig. 1, and to couple a higher car the block is turned upside down, as shown by the dotted lines in fig. 1.

The coupling-block is adjusted loosely upon the bolt, so as to allowit to oscillate to suit the motion of the cars'while running, especially while turning curves.

v The jaws of the conpling-tongue o are made to lap, and provided with square shoulders S, as shown in 2, so as to spring around and securely hold against the bolt 13, as shown in fig. l.

\Vhat I claim and desire to' secure by Letters Patent, is

The -coupling-block B, eccentrically arranged so as to change the height of the coupling, substantially as described.

In attestation of the specification of my improvement in car-couplings I hereto subscribe my name this 20th day otAugust, A. D. 1870.

JOHN MAYBEN.
